Autotransitioning

You can transition from sketching a line to sketching a tangent arc, and vice versa, without selecting the arc tool.

1. Click Line (Sketch toolbar) or click Tools > Sketch Entities > Line and sketch a line.
2. Click the endpoint of the line, then move the pointer away.
   The preview shows another line.
3. Move the pointer back to the endpoint, then away again.
   The preview shows a tangent arc.
4. Click to place the arc.
5. Move the pointer away from the arc endpoint.
   The preview shows a line. You can draw a line or change to an arc as in Step 3.

   To toggle between line and arc without returning to the endpoint, press A.
